Patent CA-2089099-A1 (CA)
Title: Broad beam flux density control
Inventor: MCINTYRE EDWARD K JR
IPC: C23C14/54
Filed: 1993-02-09
Abstract: An ion beam source (10). The source includes multiple apertures (31) bounded in close proximity by an extraction electrode (34) for extracting positively charged ions from the source, Ions exiting the source combine downstream to form a broad beam (14) which, in one utilization of the invention, is used for ion beam treatment of a silicon wafer.  Individual electrodes (40) in close proximity to the extraction electrode can be biased to either inhibit or allow backstreaming of neutralizing electrons from beam portions close to the source back to the extraction electrode. This allows the beam portion to become deneutralized and, therefore, unstable. The unstable beam is diminished in intensity since positively charged ions within that beam portion exit the beam. An isolation plate (50) separates beam portions in close proximity to the extraction electrode to inhibit beam crosstalk and an additional suppression electrode (70) common to all beam portions is controllably biased to further enhance control over beam portion intensity. In a typical application, the beam is a circular beam and intensity control is maintained to assure common intensity for a given radii from the beam center.

Patent CA-2112112-A1 (CA)
Title: Hormone-secreting cells maintained in long-term culture
Inventor: BROTHERS ANN J
IPC: G01N33/76
Filed: 1992-06-23
Abstract: Methods are provided for the establishment and maintenance in long term culture of hormone secreting cells. Cells are derived from tumorous or non-tumorous animal or human tissues, including ovary, endometrium, trophoblast, pituitary, thyroid, and pancreas.  The cells secrete into the culture medium hormones such as estrogens, progestins, follicle-stimulating hormone, luteinizing hormone, human chorionic gonadotrophin, thyroxin, glucagon, and insulin, depending on the tissue of origin of individual cell cultures.  Contact with an appropriate secretogogue causes the cells to respond with increased hormone secretion. For instance, ovarian follicular cells respond to follicle-stimulating hormone with increased estrogen and progesterone secretion. Pancreatic cells respond to elevated glucose with increased insulin secretion. The cells proliferate in in vitro for up to one year or longer, during which time they retain their hormone-secretion profile. The cells may be frozen for storage, and retain their hormone-secretion profile after thawing. The cell cultures are useful for the production of human hormones, for the bio-assay of drugs such as therapeutic gonadotrophins, for the testing of drug efficacy and design, and for toxicity testing of drugs and chemicals. The cells may also be implanted in an individual to replace deficient hormone secretion. For instance, insulin secreting pancreatic cells may be implanted in a diabetic individual as an adjunct or replacement therapy for exogenously administered insulin.
